37. The center of the Milky Way galaxy is home to a supermassive black hole called Sagittarius A*.
38. The cosmic web is a vast network of filaments and voids that form the large-scale structure of the universe.

40. Pulsars are highly-magnetized, rotating neutron stars that emit beams of electromagnetic radiation.
41. The universe is thought to be finite, but unbounded.
42. Quasars are incredibly bright and energetic centers of distant galaxies, powered by supermassive black holes.
43. The closest known exoplanet to Earth is Proxima Centauri b, in the habitable zone of its star.
44. The "Fermi Paradox" questions why, given the vast number of potentially habitable planets, we haven't detected signs of intelligent extraterrestrial life.
45. The universe is thought to be isotropic and homogeneous on large scales, meaning it looks roughly the same in all directions.
46. The largest known structure in the universe is the Hercules-Corona Borealis Great Wall, a massive cosmic filament.
47. Every element on Earth, except for hydrogen and some trace helium, was formed in the cores of stars.
48. The Perseid meteor shower occurs annually when Earth passes through the debris left behind by Comet Swift-Tuttle.
49. The event horizon of a black hole is the boundary beyond which nothing can escape, not even light.
50. The term "Big Bang" was coined by British astronomer Fred Hoyle in a radio broadcast in 1949, though he was a proponent of an alternative theory called the "steady state" model.
51. A magnetar is a type of neutron star with an extremely strong magnetic field.
52. The universe is thought to be flat on large scales, according to observations of the cosmic microwave background.
53. The largest known galaxy, IC 1101, is over 6 million light-years in diameter.
54. The first exoplanet, 51 Pegasi b, was discovered in 1995.
55. The Wow! signal, detected in 1977, remains one of the most intriguing potential extraterrestrial signals ever recorded.
56. It's estimated that there are more planets than stars in the Milky Way galaxy.
